摘要
针对某桥的拱架拼装及主拱施工过程中的整体稳定性进行有限元分析,选择施工中5个工况进行拱架整体稳定性计算,分析了这些工况的失稳模态,指出了拱架失稳的原因,为确保拱桥施工的拱架稳定性要求提供了参考依据。
This paper carries Out finite analysis of the whole stability in the process of arch centering erection and main arch construction of a certain bridge, calculates it selecting five operation conditions in the construction, analyzes their instability mods, and points out the causes of the instability, which to Offer a theoretical basis for man to ensure stability of arch centering in arch bridge construction.
